Dear experts,
I am trying to create an application in C# to extract text from pdf. I am using DAExtractPageText() method. But the text returned by this method is distorted. Some characters are missing, and blank spaces are inserted here and there within words.
Could you please tell me if it is possible to fix it?
Thank you very much,
Dmitriy

| Are you using the DLL edition or the ActiveX edition? And also, does your PDF contain any Unicode characters? |

Hi Dmitriy! Try option "0" ... The same or is it better? Generally you can say that extraction works like the textcontent was inserted. First in first out. If the first word on a page is "ello" and at the end of the page you see this and insert a "H" before the "ello", while extraction the "H" was extracted at the end of the page-content. With option "4" you can extract word by word with position-data. Regarding these position data you can contain the real textrows by your own. There's no support by QuickPDF. BTW: A small warning... Don't mix DA-functions with non-DA-functions - this won't work ;-) Cheers and welcome here, Ingo |

Hi Ingo,
Thank you for your answer. No, it is not better.
Probably that is what happened to me. And I think there is no solution for it that I could use.
Thank you very much for the warning.
May I ask one more question?
I found Quick PDF Lite. Would it support extracting images from a PDF document? I tried it, but don't know yet how to apply those methods, that are different from the Professional Quick PDF.
I would use it with C++.
Thank you very much.

Hi Dmitriy!
You can only extract images you had inserted in the same session.
No chance on other documents.
Cheers, Ingo

DAExtractPageText with Options=4 return TQuickPDF0723.AddArcToPath(CenterX, as 1 word I think now only space character is delimiter Is it possible (in future) to define more delimiters "(),.:-" I see this result tquickpdf0723. addarctopath( centerx, in software which use Adobe Acrobat Pro (acrobat = slow) |
